Abstract

La présente invention concerne un système de frein électromécanique (10) monté sur roue, avec un organe d'entraînement d'écrou (18) posé sur un étrier flottant (12) qui peut être entraîné par un moteur électrique et avec lequel un patin de frein à frottement (14) peut être comprimé contre un côté d'un disque de freinage (16), et un deuxième patin de frein à frottement (14), contre une force de réaction s'exerçant au dessus de l'étrier flottant (12), sur l'autre côté du disque de freinage (16). Pour permettre un desserrage du système de frein (10) en cas de mauvais fonctionnement, il est proposé de concevoir l'organe d'entraînement d'écrou (18) de telle manière qu'il soit anti-autobloquant, de déposer rotatifs aussi bien une vis-écrou (20) qu'un écrou fileté (22) et de bloquer l'écrou fileté (22) à l'aide d'une sécurité anti-rotation (46) détachable. En cas de défaut de fonctionnement, la sécurité anti-rotation (46) se détache et le patin de frein à frottement (14), pressé avec force contre le disque de freinage (16), exerce sur l'écrou fileté (22) une pression qui éloigne cette dernière (22) rotativement du disque de freinage (16).
